Disused Coal Mine Could Host Gravity Energy Storage Project
The title of this post, is the same as that of this article on Power Engineering International.
It does seem that Gravitricity has made a breakthrough, with the announcement of a full-size demonstration project in the Czech Republic.
- The project is based at the mothballed Staříč coal-mine in the Moravian Silesian region.
- They have backing from the European Investment Bank.
- This project will be delivered through the European Commission’s Project Development Assistance scheme.
- The Czech Republic seem to have carried out checks, with their own consultants.
It looks to me, that Gravitricity have passed the due diligence procedures of some high-powered agencies.
But this paragraph from the article must be important.
Gravitricity estimates there are around 14,000 mines worldwide which could be suitable for gravity energy storage.
If they can successfully store energy in one mine in the Czech Republic, how many of the 14,000 will be suitable for use?
I doubt it will be a small number, as mining engineers tend to be a conservative bunch and most of those mines will have been built to similar rules by similar machines and techniques.
A search of the Internet indicates that Staříč coal-mine has a depth of over a kilometre.
Using Omni’s Potential energy calculator, 12,000 tonnes and a kilometre give a figure of 32.69 MWh.
32 MWh may seem a small amount, but it would power one of these 4 MW Class 90 locomotives for eight hours.
At their typical operating speed of 100 mph, whilst hauling eight coaches, they’d travel a distance of eight hundred miles or from London to Edinburgh and back!
A Bid For The Return Of The Tweed Valley Railway Line Is At An Early Stage
The title of this post, is the same as that, of this article on the Southern Reporter.
This is the first paragraph.
A campaign for a multi-billion restoration of the Tweed Valley railway line is at an ’embryonic’ stage, a council committee has been informed.
The aim seems to be to take a restored Tweed Valley Line or Peebles Railway all the way to the Borders Railway at Galashiels station.
This map from Open Railway Map, shows the railway between Peebles and Innerleithen.
Note.
- The former Peebles Railway is shown as a dotted line.
- Peebles is in the North-West corner of the map.
- Innerleithen is in the South-East corner of the map.
This Google Map shows part of the former railway.
Note.
- The A72 at the top of the map.
- The hotel and the golf course.
- The Peebles Railway has been converted into cycling and walking route.
- The River Tweed adds a touch of serenity.
From this first glance, it looks like it would be difficult to restore the railway.
This second map from Open Railway Map, shows the railway between Innerleithen and Galashiels.
Note.
- The Borders Railway is shown in yellow.
- The former Peebles Railway is shown as a dotted line.
- Innerleithen is in the West.
- Galashiels is in the East on the Border Railway.
This Google Map shows Galashiels.
Note.
- The Peebles Railway enters Galashiels from the North-West.
- Galashiels station is in the South-East corner of the map.
- The Borders Railway is single-track through Galashiels and continues to the terminus at Tweedbank station.
These pictures show the Borders Railway through Galashiels and Galashiels station.
It was certainly a tight fit to rebuild the Borders Railway through Galashiels and there was only room for a single-track railway.
My Thoughts On A Restored Railway Between Peebles And Galashiels
These are my thoughts.
Single Or Double Track
It appears from Wikipedia that Innerleithen station was the only station between Peebles and Galashiels, that had two platforms.
Wikipedia doesn’t say, but I suspect that the Peebles Railway was single-track, except for at Innerleithen station, where there were two tracks and platforms to enable trains to pass.
I would expect that if the railway were to be restored, a similar layout could be used.
After flying my virtual helicopter along the route, I feel that it could be very difficult in some places to thread a double-track railway through the limited space.
As has been proven at Galashiels station, a well-designed single-platform station is step-free, can handle two trains per hour (tph) and is a more affordable option, as there is no bridge with lifts.
Service Frequency
I am fairly sure, that a single-track railway with a passing loop at Innerleithen, could handle two trains per hour.
But as the basic Off Peak service on the Borders Railway is hourly, I suspect that an hourly service between Peebles and Galashiels would be ideal and sufficient, as by intelligent timetabling, the interchange at Galashiels could be convenient for those going between Edinburgh and Peebles.
The Eastern Terminal
Galashiels station may only have one platform, but it is an interchange with buses to all over the Borders and there are some facilities.
One of the problems at Galashiels station, is that there may not be space for a second platform for the Peebles service, which will mean that the Borders Railway and the Peebles service may have to share the same platform.
A convenient service could probably be achieved by clever timetabling or having both trains in a lengthened platform at the same time.
You might see a sequence like this every hour at Galashiels station.
- XX:18 – Train arrives from Edinburgh and stops in the Southern end of the platform
- XX:20 – Train arrives from Peebles and stops in the Northern end of the platform
- XX:22 – Train departs to Tweedbank
- XX:32 – Train arrives from Tweedbank and stops in the Southern end of the platform
- XX:34 – Train departs to Peebles
- XX:35 – Train departs to Edinburgh
Note.
- All passengers changing trains get off one and get on the next one going to their desired destination, at the same platform
- Passengers going between Peebles and Tweedbank have two minutes to walk along the platform to change trains.
- The Borders Railway train is working the current timetable.
- The Peebles train is in the station for fourteen minutes, which should be long enough to charge the batteries, if it were a battery-electric train.
But it might be better to extend the service to Tweedbank station, where there are two platforms.
This could possibly make it easier to organise services if the Borders Railway were to be extended to Carlisle.
Journey Times
I estimate journey times could be as follows.
- Peebles and Galashiels – 21 minutes
- Peebles and Tweedbank – 25 minutes
Ideally, I suspect, if a round trip to Peebles could be under an hour, this would allow a single train to run the service.
Rolling Stock
Surely,the ideal train for this route would be one of the very light rail trains, proposed for Coventry by Warwick University, that I wrote about in Very Light Rail – A Revolution.
- These trains are single-carriage, with a capacity of fifty.
- They can run in pairs.
- They are battery-electric powered.
- They would be fast-charged at both ends.
- They have a speed of 65 mph, with good acceleration and deceleration.
- They will be highly automated.
But their biggest feature will be that they can run on a lightweight easy-to-install affordable track.
Hopefully, by the time, this railway would be installed, these trains or something similar will probably be a common sight on branch lines.
The Track
If the train can do a round trip between Peebles and Galashiels, including charging, inside an hour, then the track can be single all the way, with simple one-platform stations.
Signalling would be by the well-established principle of One-Train-On-Line, except in Galashiels station.
I also think, that if designers can get a hold on it, then an innovative design could provide all the protection needed to ensure safe operation.
Pedestrians And Cyclists
As parts of the route is now a walking and cycling track, there will probably be protests about converting the track back into a railway.
But if the design is right, I suspect that a track for walkers and cyclists can be provided alongside.
But there are other routes in the UK, where a route could be shared between very light rail, pedestrians and cyclists.
The Sheep
And then there’s the sheep!
One of the funniest scientific documents, I’ve ever seen was a serious study by Liverpool University in the 1960s, which discussed the problem of keeping sheep off the then-proposed M62 motorway. The Veterinary School of the University had done studies, that had shown sheep could climb six-foot chain link fences.
Hopefully, Scottish sheep are more sensible and better behaved than English ones.
Conclusion
Peebles and Galashiels could be an ideal route for very light rail. But parts of the design would be challenging.
However, get that design right and other routes could be converted to affordable battery-electric railways.
Gelion To Trial Battery At Spanish Solar Plant
The title of this post, is the same as that of this article on renews.biz.
This is the first two paragraphs.
Gelion has signed a test and supply contract with European renewables supplier Acciona Energia to trial its zinc-bromide battery technology at a solar plant in Spain.
Acciona Energia’s Montes del Cierzo photovoltaic solar plant in Navarra, northern Spain, will trial the energy storage system, following a competitive process launched in September 2020.
As Gelion’s Chief Executive indicates, this must be a show of confidence in their technology.
There is a full press release on the Gelion web site.
I just wonder, if Gelion could be a technology to be successful.
Royal Souvenirs Have ‘Platinum Jubbly’ Misprint
The title of this post, is the same as that of this article on the BBC.
These are the first three paragraphs.
A spelling mistake on thousands of pieces of Platinum Jubilee merchandising, calling it the “Platinum Jubbly”, is proving a challenge for souvenir sellers.
The cups and plates were meant to mark the Queen’s 70-year reign.
Clearance website boss Karl Baxter said – “in classic Del Boy-style” – he will pitch them as collectors’ items.
It is so sad that Prince Philip is no longer with us. As a Greek he would surely have had some very appropriate jokes about plate smashing.
Alice, The First All-Electric Passenger Airplane, Prepares To Fly
The title of this post, is the same as this article on CNN.
It looks like the first flight is just weeks away.
This paragraph describes the aircraft and compares it to a Boeing 737.
With battery technology similar to that of an electric car or a cell phone and 30 minutes of charging, the nine-passenger Alice will be able to fly for one hour, and about 440 nautical miles. The plane has a max cruise speed of 250 kts, or 287 miles per hour. For reference, a Boeing 737 has a max cruise speed of 588 miles per hour. The company, focused exclusively on electric air travel, hopes that electric planes that can fit 20 to 40 passengers will be a reality in seven to 10 years.
Fully electric flight on short routes is a lot closer than we think.
Note, that 440 nautical miles will give sufficient range from London to Amsterdam, Belfast, Cork, Frankfurt, Inverness and Paris.
Shell’s New Filling Station For Electric Cars
I took these pictures of Shell’s new filling station for electric cars in Fulham, yesterday.
It’s got eleven chargers, a Little Waitrose and a Costa Coffee. What more couple Fulham want?
I’m surprised the Council allowed a Costa!
Italian Group Taps CO2 For Energy Storage
The title of this post, is the same as that, as this article on Power Magazine.
It takes the form of an interview with Claudio Spadacini, who is the founder and CEO of Energy Dome.
Energy Dome will use carbon dioxide to store energy.
Technically, it looks a viable concept to me.
Are Network Rail Clearing Up The Hall Farm Curve?
I passed the Hall Farm Curve today and took these pictures.
Note.
- The truck appears to be one of Network Rail’s.
- It looks like there’s ongoing work at the other end of the chord, where it joins the West Anglia Main Line.
It’s been in a derelict state for years, so why are they tidying up now?
Northern Eden Project Worth £125 million Gets Green Light
The title of this post, is the same as that of this article on The Times.
These are the first two paragraphs.
Plans to transform the seafront of a deprived town into a £125 million northern outpost of the Eden Project have been given the green light.
Councillors in Lancashire approved plans for the site on Morecambe seafront which it is hoped will attract around a million visitors and create 400 jobs.
I think the Eden Project Morecambe could be a real Northern success.
Here’s my reasoning.
Location, Location, Location
These are the three most important factors with any house, building or property.
Morecambe has a superb location for visitors coming by car or train, as is close to both the M6 Motoway and the West Coast Main Line.
I wrote about getting to the Eden Project in Getting To The Proposed Morecambe Eden Project By Train.
I suspect visitors coming by road, would drive to a suitable Park-and-Ride and then take a train.
Lancaster Will Be A High Speed Two Station
Lancaster will be served by the following High Speed Two services.
- London Euston – Two hours and three minutes – One tph
- London Old Oak Common – One hour and fifty-six minutes – One tph
- Birmingham Curzon Street – One hour and six minutes – One tph
- Crewe – Fifty-nine minutes – One tph
- Warrington Bank Quay – Forty-two minutes – One tph
- Wigan North Western – Thirty-one minutes – Two tph
- Preston – Seventeen minutes – Two tph
- Oxenholme – Twelve minutes – One tp2h
- Penrith – Thirty-five minutes – One tp2h
- Carlisle – Fifty-two minutes – One tph
- Lockerbie – One hour and eleven minutes – One tph
- Edinburgh – Two hours and twelve minutes – One tp2h
- Motherwell – One hour and fifty-six minutes – One tp2h
- Glasgow – Two hours and twelve minutes – One tp2h
Note.
- tph is trains per hour.
- tp2h is trains per two hours.
- A shuttle train between Lancaster and the Eden Project Morecambe will probably add ten minutes.
High Speed Two will make the Eden Project Morecambe one of the best connected entertainment venues in the UK.
Avanti West Coast And TransPennine Express North Of Warrington Bank Quay After High Speed Two Opens
When High Speed Two opens, it is likely that North of Warrington Bank Quay station, the operating speed of this section of the West Coast Main Line will be faster than the current 125 mph, as the track will have been straightened and digital signalling will have been installed.
It will probably be at least 140 mph.
These trains will be running express passenger services on the route and will be able to match the speed and timings of High Speed Two’s Classic-Compatible trains to the North of Warrington Bank Quay station.
- Avanti West Coast’s Class 390 trains
- TransPennine Express’s Class 397 trains
- TransPennine Express’s Class 802 trains
There is likely to be savings of a few minutes on these services.
- Avanti West Coast – London Euston and Glasgow Central
- TransPennine Express – Manchester Airport, Manchester Piccadilly and Glasgow Central
- TransPennine Express – Liverpool Lime Street and Glasgow Central
Connections from the North-West of England and Southern Scotland will be fast and frequent.
Eden Project Morecambe Will Be A Day Trip For Greater North West England
An area defined by Carlisle, Blackburn, Manchester, Crewe, Chester, Liverpool and Blackpool will be close enough to have a day trip to the venue.
Eden Project Morecambe Is Unlikely To Be A Poor Attraction
The Eden Project Morecambe must be worth attending, but with twenty years experience of running a similar attraction in Cornwall, it is unlikely to be a failure.
Eden Project Morecambe Will Be Easier To Travel To Than The Original Eden Project For Many
I have never even been past the Eden Project in Cornwall, as it is not the easiest place to get to without a car.
I intend to go, but it will probably need two nights in a hotel to do it justice.
But Eden Project Morecambe could well be much shorter trip from London.
Currently, Avanti West Coast’s fastest time between London Euston and Lancaster are two hours and forty minutes, which would mean an under three hours trip both ways to and from Eden Project Morecambe. The Cornish site is probably nearly five hours by public transport.
Conclusion
All these factors should contribute to the success of the attraction.
Apology After Woman Dragged On Platform By London Overground Train
The title of this post, is the same as that as this article on the BBC.
These first three paragraphs describe the incident.
An investigation has been launched after a woman attempting to board a London Overground train was dragged along a platform.
The passenger tried to board the train at Wood Street Station in Walthamstow, north-east London, on 14 January when her hand got trapped in the door.
The Rail Accident Investigation Branch (RAIB) said she was then forced to run alongside the train for about 20m (66ft), before the train stopped. The woman was uninjured.
I don’t know Wood Street station or the size, shape and agility of the lady, who had the near accident.
I shall be going to have a look.
I took these pictures at Wood Street station, this afternoon.
These are my observations.
- The platforms have a very pronounced curve, which makes the gap between train and platform wider.
- There is a significant difference in the height of the train floor and the station platform, which makes the gap effectively wider.
- All the passengers getting into the train were men and wearing sensible shoes. I was too!
- There is a warning message about doors closing thirty seconds before the train leaves. I’ve never seen one before on the Overground.
I will not speculate on what caused the accident, except to say, that as the passenger wasn’t badly injured, I suspect we’ll get to the truth of what happened.
